Thanks ! The message contents look healthy. However, there are several
holes in the message sequence, from both sides. Here are all the DHCP
messages from your file:
DHCP Discover - Transaction ID 0x3938652d
DHCP Offer - Transaction ID 0x3938652d
DHCP Discover - Transaction ID 0x3938652d
DHCP Offer - Transaction ID 0x3938652d
DHCP Discover - Transaction ID 0x3938652d
DHCP Offer - Transaction ID 0x3938652d
DHCP Offer - Transaction ID 0xc2d0fd01 no discover ?
DHCP Offer - Transaction ID 0xc2d0fd01
DHCP ACK - Transaction ID 0xe89cfb5a out of thin air ?
DHCP Request - Transaction ID 0xe89cfb5a no offer ?
DHCP ACK - Transaction ID 0xe89cfb5a
DHCP Discover - Transaction ID 0x8e8a6c7d
DHCP Offer - Transaction ID 0x8e8a6c7d
DHCP Request - Transaction ID 0x8e8a6c7d
DHCP ACK - Transaction ID 0x8e8a6c7d
So there are clearly losses, at least in what your sniffer picked up.
By the way, a tcpdump on the Neo may be a more reliable source for
what's being sent and received. That would also avoid the encryption
problem.
So we come to the usual question: what does iwlist scan have to say
when at the problem places ?
I don't see any reassociations, which would be good. If you check
demsg, are there indeed none ?
Also, do you always get a rapid response with dhclient ? Maybe it's
just some weirdness in Busybox' udhcpc ...
I started to try to reproduce some of the WPA problems that have been
reported, and it seems that, if you kill wpa_supplicant and restart
it, then sometimes (*) there's a continuous stream of associations
rapidly followed by disconnects. This might also explain symptoms
like the ones you're seeing.
(*) Easy to reproduce when I'm not logging anything. Never happens
while I'm watching carefully. I think I need a book on quantum
physics :-(

Ah, but if it's a pub, then it should open early. So maybe you could
take your geek friends for a debugging session with beers, and then
hide the equipment when the rest shows up ? :-)
